Development of a multilayer fetal membrane material model calibrated using bulge inflation mechanical tests.

The fetal membranes are an essential mechanical structure for pregnancy, protecting the developing fetus in an amniotic fluid environment and rupturing before birth. In cooperation with the cervix and the uterus, the fetal membranes support the mechanical loads of pregnancy. Structurally, the fetal membranes comprise two main layers: the amnion and the chorion. The mechanical characterization of each layer is crucial to understanding how each layer contributes to the structural performance of the whole membrane. The in-vivo mechanical loading of the fetal membranes and the amount of tissue stress generated in each layer throughout gestation remains poorly understood, as it is difficult to perform direct measurements on pregnant patients. Finite element analysis of pregnancy offers a computational method to explore how anatomical and tissue remodeling factors influence the load-sharing of the uterus, cervix, and fetal membranes. To aid in the formulation of such computational models of pregnancy, this work develops a fiber-based multilayer fetal membrane model that captures its response to previously published bulge inflation loading data. First, material models for the amnion, chorion, and maternal decidua are formulated, informed, and validated by published data. Then, the behavior of the fetal membrane as a layered structure was analyzed, focusing on the respective stress distribution and thickness variation in each layer. The layered computational model captures the overall behavior of the fetal membranes, with the amnion being the mechanically dominant layer. The inclusion of fibers in the amnion material model is an important factor in obtaining reliable fetal membrane behavior according to the experimental dataset. These results highlight the potential of this layered model to be integrated into larger biomechanical models of the gravid uterus and cervix to study the mechanical mechanisms of preterm birth.

Metabolic and Dietary Factors in Acne Vulgaris and Evaluation of the Acne Vulgaris Treatment with Oral Contraceptive-Based Therapies in Young Adult Women.

The etiopathogenesis of acne is complex, as several endo- and exogenous factors that affect the sebaceous-hair unit are involved in the development of acne lesions. The main aim of the study was to evaluate selected metabolic parameters before treatment. Another goal of the study was to determine the correlation between selected metabolic and dietary parameters and the severity of acne before treatment. The third objective was to assess the severity of acne before and after treatment, considering the type of treatment used. The final objective was to assess the relationship between the difference in acne severity before and after treatment, considering the type of treatment used and factors of dairy or sweets intake. 168 women participated in the study. The patients belonged to two groups: the study group (99 patients with acne vulgaris) and the control group (69 patients without skin lesions). The study group was divided into subgroups according to the treatment used: contraceptive preparation, contraceptive preparation and cyproterone acetate, and contraceptive preparation and isotretinoin preparation. We found that LDL levels and consumption of sweets correlated with acne severity. The mainstay of acne treatment is contraceptive treatment (ethinylestradiol and drospirenone). The effectiveness of the three contraceptive-based treatments was confirmed by observing the severity of acne. There were no significant correlations between the difference in acne severity before and after treatment with the three treatments and factors of dairy or sweet consumption.

Late Diagnosis of Swyer Syndrome in a Patient with Bilateral Germ Cell Tumor Treated with a Contraceptive Due to Primary Amenorrhea.

Swyer syndrome is a special form of DSD (disorders of sex development), so-called pure gonadal dysgenesis with a karyotype 46, XY and a female phenotype. One of the most important problems in patients with DSD is the risk of gonadal tumors. We present a case of a 26-year-old patient with Swyer syndrome. The patient had primary amenorrhea and no puberty characteristics. In ultrasound imaging in the vicinity of the uterus, there were two homogeneous structures. A genetic diagnosis was also performed, which showed karyotype 46, XY. The patient underwent a bilateral gonadectomy. Histopathological examination revealed the presence of dysgerminoma in both dysgenetic gonads. The follow-up of five years now did not show any changes suspected of invasion. We concluded that the primary amenorrhea, along with the absence of development of sexual characteristics, should prompt an expanded diagnosis for disorders of sex development. Gonadal dysgerminoma should be suspected even in the absence of tumor features on ultrasound and blood laboratory tests. Early prophylactic gonadectomy could protect patients from developing tumors in dysgenetic gonads.

Case report: Hydrometrocolpos conditioning recurrent urinary tract infections.

We present a case of a 12.5-year-old girl who has suffered from recurrent urinary tract infections for many years but has never undergone a detailed diagnostic process. Only as a teenager did she complain of acute pain in her lower abdomen and it turned out that her genital organs had not properly developed. She had an obstructive defect in the reproductive tract. When there was a significant amount of discharge collected in the lumen of the genital tract and the organs had distended, acute pain appeared, which allowed us to make the diagnosis. In the diagnostic process, transperineal ultrasonography turned out to be extremely helpful, allowing us to establish the type and thickness of the obstruction. The patient underwent excision of transverse vaginal septum, and postoperative silicon dilators were used to prevent the recurrence of the obstruction. There was no recurrence of urinary infection or complications during the 11 months of follow-up.

The impact of EAES Fellowship Programme: a five-year review and evaluation.

BACKGROUND: The European Association of Endoscopic Surgery (EAES) fellowship programme was established in 2014, allowing nine surgeons annually to obtain experience and skills in minimally invasive surgery (MIS) from specialist centres across the Europe and United States. It aligns with the strategic focus of EAES Education and Training Committee on enabling Learning Mobility opportunities. To assess the impact of the programme, a survey was conducted aiming to evaluate the experience and impact of the programme and receive feedback for improvements. METHODS: A survey using a 5-point Likert scale was used to evaluate clinical, education and research experience. The impact on acquisition of new technical skills, change in clinical practice and ongoing collaboration with the host institute was assessed. The fellows selected between 2014 and 2018 were included. Ratings were analysed in percentage; thematic analysis was applied to the free-text feedbacks using qualitative analysis. RESULTS: All the fellows had good access to observing in operating theatres and 70.6% were able to assist. 91.2% participated in educational activities and 23.5% were able to contribute through teaching. 44.1% participated in research activities and 41.2% became an author/co-author of a publication from the host. 97.1% of fellows stated that their operative competency had increased, 94.3% gained new surgical skills and 85.7% was able to introduce new techniques in their hospitals. 74.29% agreed that the clinical experience led to a change in their practices. The most commonly suggested improvements were setting realistic target in clinical and research areas, increasing fellowship duration, and maximising theatre assisting opportunities. Nevertheless, 100% of fellows would recommend the fellowship to their peers. CONCLUSION: EAES fellowship programme has shown a positive impact on acquiring and adopting new MIS techniques. To further refine the programme, an individualised approach should be adopted to set achievable learning objectives in clinical skills, education and research.

Wound dehiscence prevalence and relationship with prosthetic material extrusion in women underwent anterior colpotomy.

AIM: To assess the prevalence of anterior vaginal wall dehiscence in women who underwent anterior vaginal wall colpotomy for pelvic organ prolapse or stress urinary incontinence and to evaluate the influence of suture materials and techniques on wound dehiscence. MATERIALS AND METHODS: This multicenter, prospective study enrolled naïve women for urogynecological surgery affected by anterior vaginal wall defect or stress urinary incontinence. Performed surgical procedures were anterior vaginal wall repair (AVWR) with native tissue (N-AVWR) or polypropylene mesh (M-AVWR), trans-obturator polypropylene in-out middle urethral sling (MUS). Used suture materials were Vicryl 2-0, Vicryl Rapide 2-0, and Monocryl 3-0. Suture techniques were running interlocking or interrupted. Follow-up was performed daily during hospitalization and in outpatient clinic after 10-14, 30 days, and after 3 months. RESULTS: A total of 1139 patients were enrolled. AVWR were 790: 89.1% N-AVWR, and 10.9% M-AVWR. Polypropylene MUS were 349. Women with prosthetic implantation were 38.2%, while 61.8% had native tissue repair. Overall Vicryl was used in 53.9%, Vicryl Rapide in 37.4%, and Monocryl in 8.7%. Overall running interlocking sutures were 66.5%, while interrupted were 33.5%. Overall wound dehiscence prevalence was 0.9% (10/1139). Wound dehiscence rate of 0.6% (5/790) was documented in AVWR: 0.3% (2/704) in N-AVWR, and 3.5% (3/86) in M-AVWR. Among women underwent MUS, 1.4% (5/349) showed wound dehiscence. In patients who underwent prosthetic surgery, the overall dehiscence prevalence was 1.8% (8/435). A statistically significant higher rate of wound dehiscence was found in women with implanted prosthetic materials. DISCUSSION: We reported for the first time the prevalence of wound dehiscence in females who underwent colpotomy for AVWR or MUS. Wound dehiscence occurrence was low, but non-negligible. We found that this complication was poorly associated to the suture methods and materials, while prosthetic material represented a risk factor for wound healing.

[Probiotics intake as gut-microbiota modulating therapy in an interdisciplinary aspect]. / Rola probiotyków jako modulatora regulacji zaburzen mikroflory jelitowej w podejsciu interdyscyplinarnym.

The gut microbiota was defined as one of the endocrine organs. It consists of many various microorganisms with huge metabolic potential. An imbalance of the gut microbiota was assessed as one of risk factors for various metabolic, infectious, and inflammatory disorders, but also stress-related disorders. Link between the gut microbiological environment and the development of such pathologies as: metabolic syndrome, diabetes, obesity, inflammatory bowel disease, colorectal cancer, depression, anxiety disorders, attention deficit hyperactivity disorder or PCO syndrome has been proven. Diet with probiotics intake could be effective in the prevention and treatment of many diseases and associated metabolic disorders. Increasing the amount of "beneficial" gut microbiota may favorably affect the functioning of the whole organism. Treatment options for specific diseases must be compliant with the guidelines of recommendations for these disorders. However, probiotic supplementation can positively strengthen the results of this treatment. It is recognized that probiotics, by increasing beneficial intestinal microflora, inhibit development of pathogens and change metabolic and enzymatic activity. It reduces inflammation and positively regulates immunologic activity of intestines. On the base of conducted studies beneficial effects of probiotic supplementation in patients with metabolic, endocrine and mental disorders were noted. Prebiotics and probiotics influence on modification of gastrointestinal microflora. Changes of gut microbiota, by diet with probiotics intake, cause the maintenance of gut epithelial barrier integrity and may be useful in prevention and treatment of many diseases and concomitant metabolic disorders. It may have potential implications for protection against adverse, long-term health consequences of these disorders.

Assessment of Overactive Bladder after Laparoscopic Lateral Suspension for Pelvic Organ Prolapse.

BACKGROUND: Pelvic organ prolapses (POP) and overactive bladder (OAB) may coexist and both negatively impact quality of life in women. The correlation between POP and OAB remains unclear, but these patients may have the OAB resolution after the surgical treatment of POP. Aim of our study was to assess the anatomical results and the effect on OAB symptoms in women who underwent laparoscopic lateral suspension for POP. MATERIALS AND METHODS: This prospective study included all women with apical POP who underwent surgical repair with laparoscopic uterine lateral suspension from January 2016 to December 2017. The baseline and the 1-year follow-up included post-void residual measurement, urinalysis, vaginal examination, OAB symptoms evaluation, and administration of questionnaires (PFDI-20, UDI 6). RESULTS: 64 women underwent laparoscopic lateral suspension for uterine prolapse and 78.1% had concomitant anterior vaginal wall defect. At 1-year follow-up the anatomic success rates were 84.4% for the apical and 76.2% for the anterior compartment. The comparison between OAB symptoms before and after the surgical procedure showed the resolution of OAB in 76% of the women, while de novo OAB was present in 2.6%. With the questionnaires 95.3% (61/64) of our patients were satisfied after the POP repair. We documented a trend in ameliorating of OAB regardless of the POP-Q stage. However, the Pearson test showed this correlation as statistically significant only in women with anterior vaginal wall defect stage III and apical stage II. No patient had vaginal exposure of the polypropylene mesh. CONCLUSION: Our data show how laparoscopic lateral suspension is an effective procedure for apical and anterior vaginal wall defects. This study provides further evidence for the concept that OAB in women with POP >II stage improves after a successful POP surgery. These women may benefit from a resolution of OAB and POP symptoms with the improvement of patient's quality of life.

Laparoscopic approach to pelvic organ prolapse - the way to go or a blind alley?

Pelvic organ prolapse represents a relatively frequent diagnosis that requires attention due to its detrimental effect on quality of life. Not surprisingly, it is one of the commonest indications for surgery in premenopausal and postmenopausal women, often requiring a complex multidisciplinary approach. Traditional vaginal procedures are being gradually replaced by laparoscopic techniques, offering anticipated benefits in reduced recurrence and complication rates, while respecting the trend towards uterus sparing if desirable. Recently, questions about the safety of alloplastic materials used in pelvic organ prolapse surgery were raised, leading to official restrictions in their use, particularly for transvaginal application. As a result, laparoscopic procedures might appear slightly favored but caution must be taken to assure proper technique of mesh placement while maintaining high awareness of possible long-term mesh-related complications that require close surveillance. Therefore, adequate education and training becomes even more important to achieve optimal results and to avoid possible serious medico-legal charges.
